WD Red Pro WD181KFGX 18TB 7200 RPM 512MB Cache SATA 6.0Gb/s 3.5″ Internal Hard Drive

Larger NAS Bay Shock Protection

WD Red ^™  Pro NAS HDDs are equipped with a multi-axis shock sensor that automatically detects subtle shock events and dynamic fly height technology which adjusts each read-write function to compensate and protect the data. This combination of technology further protects the drives in larger 24-bay NAS environments and helps increase hard drive reliability.

3D Active Balance Plus

Our enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over time.

Error Recovery Prevention

Built specifically for RAID and NAS environments, WD Red ^™  Pro NAS HDDs come equipped with error recovery controls as part of NASware ^™  3.0 technology to help reduce drive fallout in RAID applications.

Extended Drive Testing

A NAS environment that has up to 24 bays is very demanding on a hard drive with added vibration and heat. This is why every WD Red ^™  Pro drive is shipped with extended thermal cycle burn-in testing to help ensure each drive is tested for extended reliable operation.

Longer Warranty Coverage

WD Red ^™  Pro NAS hard drives comes with a 5-year limited warranty for an even greater peace of mind.

Desktop Drives Vs. WD Red ^™  Pro

Do right by your NAS and choose the drive purpose-built for NAS with an array of features to help preserve your data and maintain optimum performance. Take the following into consideration when choosing a hard drive for your NAS:
• Compatibility: Unlike desktop drives, these drives are specifically tested for compatibility with NAS systems for optimum performance.
• Reliability: The always-on environment of a NAS or RAID is a hot one, and desktop drives aren’t typically designed and tested under those conditions like WD Red ^™  Pro drives are.
• Error Recovery Controls: WD Red ^™  Pro NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system.
• Noise and Vibration Protection: Designed to operate solo, desktop drives typically offer little or no protection from the noise and vibration present in a multi-drive system. WD Red ^™  Pro drives are designed to thrive in multi-bay NAS system environments.
